Large vertical self-aligning bearings with housings, with shaft diameters ranging from 150 to 450 mm, feature a reinforced, thickened housing and a precision bearing unit. They offer excellent load-bearing capacity, a robust structure that resists deformation, and stable self-aligning compensation, making them suitable for heavy-load, low-speed continuous operation; With robust construction and high impact resistance, they are suitable for supporting the rotating shafts of heavy-duty equipment with large shaft diameters, such as heavy industrial machinery, mining machinery and large conveyor lines, making them a reliable component for the transmission systems of large-scale mechanical equipment.
